PROFINET

Company-wide automation and uniform communication with PROFINET, the open Industrial Ethernet Standard from PROFIBUS International.

Application Example "Diagnostics Procedure for PROFINET Network Components"

A PROFINET I/O system with various network components is to be monitored. The automation solution comprises a PROFINET IO Controller, an HMI station as well as a SCALANCE X208, a SCALANCE X202 and two ET 200S PN FO modules as PROFINET devices. In addition to individual diagnostics of the components, it should also be possible to provide detailed diagnostics of the complete system. The application example comprises documentation and program code.

Typical Response Time on PROFINET

PROFINET configuration with I/O controller and I/O device

Many applications call for a fast response time via the distributed I/Os. To exchange data quickly and efficiently between the distributed I/O and S7 stations, the SIMATIC uses PROFIBUS DP and also PROFINET IO. Typical PROFINET IO configurations consist of an I/O controller with several I/O devices, whereby programming devices (PG) or HMI devices (panels) are used on the Industrial Ethernet. One of the most important questions concerning the arrangement of such configurations relates to the expected response times.

SIMATIC ET 200M Available for PROFINET

The

IM 153-4 PN interface module now enables connection of the ET 200M distributed I/O system to PROFINET. In addition, the 153-4 module has an interface with integral 2-port switch and T functionality in the power supply. Up to 12 modules can be plugged in within one station, saving space in the control cabinet. The channel density can also be significantly increased by 64-channel modules (

64 DI and

64 DO).

White Paper: PROFINET in the Process Industries

Having proven its value in factory automation, industrial Ethernet is now emerging as a viable solution in the process industries as well. A new ARC White Paper entitled

"PROFINET in the Process Industries" appeared in April 2007.

SIMOTION V4.1 and PROFINET for High Performance in Machine Automation

Version 4.1 of the SIMOTION Motion Control System features

extended PROFINET functions for modular machine concepts, enabling electrical and hydraulic drives to be synchronized with each other. In addition, controllers can be configured simultaneously at the same PROFINET interface as IO Controller and IO Device. By means of controller-controller communication via PROFINET, SIMOTION V4.1 permits axis synchronization between several controllers.
